You have a right to access personal data you've provided to us and to correct, update, or delete such data. You can also export a copy of content in your Google Account if you want to back it up or use it with a service outside of Google.
These rights are legally required under GDPR (Arts. 15-20) and CCPA, and Google's implementation of them through self-service tools means consumers can actually exercise meaningful control over their data if they know these tools exist.
Google collects a wide range of personal data including location history, search queries, emails (for feature delivery), browsing activity on third-party sites via Google's ad network, voice and audio data, and device identifiers, combining these across all Google services to build detailed user profiles. This cross-service data combination powers Google's advertising business and means your activity on one Google product can influence what you see on entirely different products and third-party websites. You can review and delete your data, turn off ad personalization, and manage location history at myaccount.google.com/data-and-privacy.
